A number of personnel have been rendered un-deployable by their condition and many of the HIV sufferers have been discharged.

Some 9,341 infections were recorded overall. That includes 8,334 male and 957 female troops.

The fact that some troops had multiple infections lowers the figure slightly, bringing the toll to 9,291 individual troops.

The Army suffered the greatest prevalence, with 5,854 men and 534 women catching a dose. The Royal Navy registered 1,879 and the RAF came third with 1,609.

Chlamydia was the most prevalent disease with 3,803 troops – 3,347 men and 456 women – diagnosed, most commonly among the under-25 age group.

Some 1,080 troops suffered genital herpes, 1,848 contracted genital warts and 127 were found to have one of the two common strains of Hepatitis. Meanwhile 2,641 were diagnosed with pelvic inflammatory disease and 141 troops were found to have either syphilis or gonorrhoea.

“Most unit medical officers will freely hand out condoms to troops who are constantly warned about the dangers of unprotected sex,” one senior officer told the Mirror.

“There are plenty of posters around most bases warning of the dangers of STDs – some of these diseases such as HIV can be career ending,” he added.

While these figures are high, available World War I records show that over the course of the 1914-1918 conflict venereal diseases saw 416,891 British and Dominion soldiers were hospitalized.

The figure is striking when compared to 74,711 cases of Trench Foot – a disease much more commonly associated with the Great War.
